      SD Support

      For the RRD GLCD it CANNOT share the same SPI as the LCD so it must be
      hooked up to the onboard SDCard SPI and use a spare pin for the SDCS.
      Also note that an external SDCard sharing the SPI port with the
      onboard/internal SDCard must be ejected before rebooting as the bootloader
      does not like the external card. NOTE Smoothie will not boot if the external
      sdcard is inserted in the RRD LCD sdcard slot at boot time, it must be
      inserted after it has booted.
